Recent reports of new locally transmitted COVID-19 cases on the Chinese mainland have served to boost the vaccination demand.

The record for daily COVID-19 vaccine doses administered was broken four times between May 13 and 17, with the daily total exceeding 12 million throughout the period, according to the commission.
